After 1950s - 

Machine Rolled Filtered Cigarettes

• Machine Rolled cigarettes consisting mainly of a tobacco blend, paper, PVA glue to bond the outer layer of paper together, and a based filter
• Machine rolled cigarettes were blended, using a mixture of different tobaccos to create a bright or robust flavor. The different tobaccos will most likely be derived from various cuts and have differing tastes. Having multiple different types of Tobacco is what gives a blend’s smoke a robust flavor
